Guzman (22-0, 22 KO) demolished Shingo Wake for the title in July, going a career-long eleven rounds and dropping him four times before the referee stepped in. The Dominican is just twenty-seven.

Oguni (18-1-1, 7 KO) is 8-0-1 since falling to Wake in 2013 and ranked #7 by BoxRec. That said, two of those nine guys were making their debuts. Not the best preparations for possibly the biggest puncher at 122.

The fight is Japan’s fourth scheduled world title fight so far on that date. In Tokyo, Jezreel Corrales rematches Takashi Uchiyama for the WBA “Super” super featherweight title and Ryoichi Taguchi defends his WBA light flyweight title against Carlos Canizales. Moises Fuentes faces Kosei Tanaka for the vacant WBO light flyweight title, formerly held by Donnie Nietes, in Gifu.
